MACHINE F OR LOADING COAL, 840.

SPECIFICATION forming part of Letters Patent N 0. 681,142, dated August 20, 1901. Application filed February 5, 1901. Serial No. 46,116. (No model.)

To nJZ whom, it may concern.-

Be it known that I, HENRY JEROME SEITZ, of the city and county of Philadelphia, State of Pennsylvania, have invented an Improve ment in Machines for Loading Coal, &c., of

which the following is a'specification.

My invention has reference to machines for loading coal, &c.; and it consists of certain improvements fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide a machine adapted for the handling of coal,

sand, lime, &c., in yards where it is necessary to load wagons from a dump, whereby it may be automatically raked down from the dump, elevated, screened, if desired, and deposited in the wagon.

In carrying out my invention I provide a :0 portable at an elevation, an elevator forelevating the materials into the chutes, and an adjustable raking-down device for feeding the materials to the elevator. suitable screening devices for screening the material from dirt on its way to the wagon and preferably while passing through the chute, and, if desired, it may have convenient motive power for giving to it mobile capacity, whereby it may be transferred to different parts of the yard or dump or to difierent dumps where difierent grades of the same material or different kindsof material are to be successively handled.

V 5 My invention will be better understood by reference to the drawings, in which:-

Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a crosssectional elevation of same on line 2 2, and

0 Fig. 3 is a sectional line 3 3.

A is the main frame of the apparatus and is preferably supported upon two propellingwheels B B and one pair ofsteering-wheels C,

5 jo'urnaled in a pivoted truck or fifth-Wheel O, which may be turned by chain or cable a and hand-wheel and shaft C. On the main frame A is a boiler D and a steam-engine d,'

the latter driving a shaft E by sprocket-chain 5o transmission g. The shaft E drives the wheels B by sp'rocket-chain-power transmisvehicle having, discharging-chutes- M yapparatus may also have plan view of same on sion 1). Clutches B enable either of the wheels B or both to be driven in propelling or steering the apparatus for shifting its position. It is also evident that when the right position is taken both clutches maybe thrown out of action, in which case the rotation of the shaft E will have no effect in propelling the apparatus and at this time employed only in handling the coal, (to. .Ofcourse it is evi- 6o dent that in place of a steam-engine any other type of well-known motive power may be employedsuch as an electric motor,compressed air engine, or gas or gasolene engine-as found most convenient and economical.

The main frame is provided with a superstructure A,upon which is built a doublechute structure I, having gates L upon opposite sides of the ridge 2', adapted to be operated by hand through the levers I. These gates may be made in any other convenient manner.

H represents endless chains carrying buckets 71., forming the elevator. They are guided at the bottom by the wheels F and at the top 7 5 by wheelsf and F the chains moving in a triangular path. I, however, do not limit myself to any special number of guide-wheels for the elevator. The elevator lifts the coal, and when fully elevated it passes horizon- 8 tally over the ridge of the chutes I and discharges its coal into the said chutes. The wheels f are fast upon a shaft F, and this is driven by the shaft E through the sprocketchain-power transmission G. Aclutch tmay 8 be employed on shaft E for throwing the transmission-chain G into or out of action,

as desired. The lower wheels F for the elevator are secured to a shaft m, carried in suitable bearings in the main frame A, and to this shaft is hinged the boom-frame M, having I the endless chains P, provided with scrapers 19. One part of these chains pass about sprocket-wheels O on a shaft N. and the other part about sprocket-wheels O on a shaft Q, 5 which latter is adjustable by screw adjustment R to or from the wheels 0 for varying the tension of the chains or for permitting their removal for making repairs. The shaft N is driven from shaft N by gearing N and shaft N is driven from shaft m by sprocketchain transmission 17.. The angle of the boom.

S or any other M- may be adjusted by the block and tackle suitable adjusting means;

The raking-conveyer'l p feeds the coal downward and backward toward the elevator H, and it is guided into the buckets it thereof by the shoe T, which extends under and forward of the wheels F This shoe T may be extended upward and rearward, as at T, to act as an inclined chute through which the return portion of the elevator passes and by which it is shielded.

If desired, the chutes I may be provided with screens J for screening the coal on its way to the wagon, the refuse passing down into the hoppers K, from which it may be withdrawn by doors 1c from time to time.

Asshown, the apparatus may cause the elevated coal to be discharged from either or both chutes I at a time, so as to simultaneously load two wagons where that is necessary.

By use of this apparatus I have found that there is great saving in time and labor over what is required to perform the same amount of work by hand labor, and therefore secures great economy. The saving in time is very important where a dealer has to make many deliveries in a day, as it permits amaximum duty at a minimum of time and expense and with less wagons and men than would otherwise be necessary.

\Vhile I prefer the construction herein set out, I do not limit myself to the minor details thereof, as they may be modified in various ways without departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:
